Fake trees could help in the fight against climate change

One of the best ways to fight climate change is to invest in trees and plants. Branches and leaves help trap carbon dioxide, effectively reducing overall pollution in the atmosphere. The only hurdle is that trees take up a lot of land and resources to cultivate, which is why scientists are turning to an alternative source in the fight against carbon emissions. Scientists in Germany just published a new study about how artificial plant life can also cut down on carbon pollution . The team created an artificial system that absorbs carbon dioxide and turns it into a product that is rich in carbon, like alcohol. The system then releases oxygen into the air and captures any excess carbon byproducts for later use. Related: How to teach children about climate change The artificial system is actually more effective than what plants and trees do naturally. In fact, some experts believe this new technology is about 1,000 times better than its natural counterpart. This is significant, because there is not enough room on the planet for trees and plants to absorb the amount of carbon we are currently emitting into the atmosphere. Although artificial trees might be the answer to help curb carbon emissions, there is one catch to the system. According to The Guardian , the cost of installing artificial trees is beyond the reach of most communities. Starting a small forest of artificial trees costs close to a quarter of a million dollars, and that is just to get the ball rolling. Scientists hope to decrease that price point in the near future, but that will only happen once technology progresses and investors get more interested in funding research. If scientists can lower the cost of artificial trees, then it might be our best option for capturing  carbon emissions. But this technology is competing against other methods of removing carbon from the air, so only time will tell if artificial systems are the answer to the growing problem of climate change.

Comments Off on Carbon removal is our best hope to deliver on the Paris Agreement

To limit global warming to no more than 2 degrees Celsius, we’ll need to do more than reduce emissions. We’ll have to remove some carbon from the atmosphere — as a number of pioneering companies realize.

Comments Off on Massive Los Angeles methane leak declared permanently sealed

Since October, an underground natural gas storage well in Aliso Canyon , California has been belching up thousands of pounds of methane into the atmosphere every hour while the Southern California Gas Company desperately scrambled to close up the leaky pipe casing. Last week, it seemed the leak had finally been plugged , and today SoCal Gas confirmed that the leak has been permanently sealed .

Comments Off on New carbon nanofiber process could reduce atmospheric C02 to pre-industrial levels in just a decade

Imagine being able to turn pollution into something useful while returning the planet to pre-industrial carbon levels in just ten years. Scientists believe that it’s possible: a new process developed by team at George Washington University could manufacture the fibers using carbon dioxide extracted from Earth’s atmosphere – talk about a win/win for everyone. The double-whammy discovery could help tackle climate change , while revolutionizing many industries. According to Gizmag , carbon nanofibers could one day be used for everything from building better bulletproof vests to fixing damaged hearts, not to mention making a big dent in climate change.   Read the rest of New carbon nanofiber process could reduce atmospheric C02 to pre-industrial levels in just a decade

New study confirms global warming is making California’s drought worse

Comments Off on New study confirms global warming is making California’s drought worse

Climate scientists have been keeping a close eye on the years-long drought plaguing California , looking for clues that might suggest how to cope with or even reverse the drought conditions. Although droughts occur from time to time over the course of history as part of natural cycles, scientists said Thursday that global warming has had a direct and severe impact on the current drought , making it much more severe than it might be otherwise. And, of course, the droughts aren’t the only consequence of human-caused climate change. Read the rest of New study confirms global warming is making California’s drought worse

Better Cement for Construction with Less CO2

Comments Off on Better Cement for Construction with Less CO2

Greener cement for construction may be already well within reach, based on a new study carried out by researchers from MIT in the United States and CNRS in France.  While modern-day cement has its roots extending back to the mid-1700s, the ratios of the two main ingredients, calcium (from limestone) and silica (from clay), which are used to manufacture it can vary widely, and had not been studied to this extent before. The potential reduction in carbon emissions from the production of cement could be as much as 60 percent, according to Dr. Roland Pellenq, the senior research scientist for the study.  The production of cement is presently one of the largest contributing industrial sources of CO2 in the atmosphere.  Consequently, changes in its manufacture could have significant and widespread benefits if a better production method is developed. “In conventional cements, Pellenq explains, the calcium-to-silica ratio ranges anywhere from about 1.2 to 2.2, with 1.7 accepted as the standard. But the resulting molecular structures have never been compared in detail. Pellenq and his colleagues built a database of all these chemical formulations, finding that the optimum mixture was not the one typically used today, but rather a ratio of about 1.5.”  Production of cement at this ratio would, according to the researchers, allow significant reductions in CO2 emissions.  In addition to the emissions benefit, the researchers also found that cement produced at this ratio would be stronger and more fracture resistant. Adaptation of this research will still take time to implement, as the new formulations will need to be studied by engineering standards organizations before this becomes the new standard for manufacture. There could even be a synergistic benefit in this, by significantly reducing the carbon emissions in the production of the cement, and then further reducing emissions due to less cement being needed due to the improved strength of the material. via: MIT Press Release image credit: Phlat Phield Photos
